4.1 Shrubveld on mountains, hills, slopes and crests The vegetation on the slopes and crests of the mountains and hills (Figure 15) is a shrubland with both succulent and non-succulent bushes and a sparse grassy layer. The geology is varied and complex with metamorphic rocks consisting of clastic sediments, volcanic and intrusive rocks of Mokolian age. The land type is mostly Ib and Ic, indicating the shallow rocky or gravelly soils. The most prominent or general species found in this vegetation include the following: Trees, Shrubs and Dwarf shrubs and Succulent Shrubs Adromischus diabolicus Aloe dichotoma P Nymania capensis Othonna euphorbioides Boscia albitrunca P Ozoroa dispar Boscia foetida Ehretia rigida Eriocephalus pauperrimus Euphorbia avasmontana Euphorbia gariepina Euphorbia gregaria Ficus ilicina Kleinia longiflora Lycium cinereum d Pappea capensis Pteronia unguiculata Rhigozum trichotomum Salsola aphylla Sarcostemma viminale Searsia undulata Tetragonia reduplicata Tylecodon rubrovenosus Tylecodon sulphureus D d Grasses Aristida adscensionis Aristida congesta Digitaria eriantha Enneapogon desvauxii Eragrostis annulata Eragrostis nindensis Oropetium capense Stipagrostis obtusa D Forbs Acanthopsis hoffmannseggiana Anacampseros karasmontana Aptosimum spinescens Blepharis mitrata Blepharis pruinosa Ceraria namaquensis Chascanum garipense Conophytum fulleri Conophytum sp Cotyledon orbiculata SATO Aggeneys July 2011 54
Crassula sericea Dicoma capensis Cucumis rigidus Drosanthemum godmaniae Dyerophytum africanum Galenia fruticosa Helichrysum tomentosum Hermannia stricta Hermbstaedtia glauca Hibiscus elliottiae Hirpicium alienatum Hoodia gordonii Monechma spartioides Osteospermum armatum Pelargonium spinosum Rogeria longiflora Ruschia robusta 4.2 South facing slopes The high and steep south facing slopes are considered as an important plant community (Anderson 2000, Desmet 2010). The vegetation on the steep south-facing slopes is dense shrubveld and very low cover of grass species. Due to the cooler south-facing slopes and availability of moisture in winter, this vegetation is regarded by Desmet (2010) as a remarkable outlier of Succulent Karoo vegetation and shows some similarity to the Namaqualand Klipkoppe Shrubland. It is therefore considered as being floristically very important and is regarded as highly sensitive. 4.2.1 South-facing scree slopes The most prominent or general species found in this vegetation include the following: Trees, Shrubs and Dwarf shrubs and Succulent Shrubs Aloe dichotoma P Euphorbia gariepina Boscia foetida Cadaba aphylla Chrysocoma ciliata Cineraria alchemilloides Didelta carnosa Diospyros ramulosa Eriocephalus microphyllus Eriocephalus scariosus Euphorbia avasmontana Euphorbia mauritanica Haworthia venosa Huernia campanulata Montinia caryophyllacea Nymania capensis Ozoroa dispar Pentzia lanata Pteronia leucoclada Rhigozum trichotomum D SATO Aggeneys July 2011 55
